Hope you find one that works for you... I changed mine out on both of the LRH barrels but I have forgotten what I did...
If you can find them might check out the Speer Gold Dot line... These bullets are bonded and do not come apart... "poorman's nosler/barnes"
If you prefer to shoot 44 cal bullets - Speer makes a .429/270 grain soft point Gold Dot - which is really a good bullet. I would shoot the .452/250 for deer and the .452/300 for elk.
